5 Ways to Get Rid of Earworms, According to Science

The 19-year old undergraduate arrived at the student health center with an unusual complaint: Music had been stuck in his head for the past three years, and he could no longer cope. There was never just silence.

According to Dr. Zaid Yusufi Rafin, the psychiatrist that reported the case [PDF], it was a rare long-term manifestation of a pernicious earworm—a tune that gets stuck in your mind without your wanting it to. The student was able to reduce his earworms with cognitive-behavioral therapy, but short of a visit to the doctor, what can the rest of us do to rid ourselves of them? Here are five strategies, backed by science.

1. LISTEN TO THE ENTIRE SONG.

Earworms tend to be small fragments of music that repeat over and over (often a song’s refrain or chorus). A 2014 study evaluated existing surveys of people’s methods for coping with earworms and found that one of the most effective behaviors is just listening to the whole tune. Participants said they actively engaged with the offending music: They hummed or sang it, figured out the tune’s title and the name of the singer, or listened to the full song instead of the unwanted snippet. Some people listened to other music immediately after the ending of the earworm-generating tune as well.

2. LISTEN TO A “CURE TUNE.”

The same study also found that some subjects used competing songs, or “cure tunes,” to control their earworms. The researchers identified 64 such tunes, with six of them named by more than one person: “Happy Birthday to You,” “God Save the Queen” (the participants in the survey were British), The A-Team theme, “Sledgehammer” by Peter Gabriel, “Kashmir” by Led Zeppelin, and “Karma Chameleon” by Culture Club. In most cases, the cure tunes suppressed the earworms without becoming earworms themselves. In the rare occasions when they did, people said that they preferred to have the cure tunes stuck in their heads.

3. DISTRACT YOURSELF WITH SOMETHING ELSE.

Our brains are incapable of paying attention to more than one thing at a time, so any attempts to multitask are neurally doomed to failure. This limitation can be helpful when it comes to earworms. Strategies involving words, rather than music, can help nudge your brain away from the earworms and towards something else. Some effective remedies include talking with other people, meditation, prayer, watching TV, and reading.

4. CHEW GUM.

In a 2015 study, researchers suspected that the act of chewing gum might interfere with the formation of the auditory imagery needed to experience an earworm. How? Chewing might hinder the motor programming involved in speech articulation, and therefore could keep people from subvocalizing (saying the words to the songs in their heads). They found that vigorous gum-chewing did reduce the number of unwanted musical thoughts, but noted that not just any kind of motor activity leads to earworm reduction. When the study participants tapped their fingers upon the desk, they had more persistent earworms than when they chewed gum.

5. LEAVE IT ALONE.

Despite earworms’ involuntary and intrusive nature, research indicates that people actually don't mind them that much. A daily diary study concluded that only a small percentage of earworms interfered with daily activities, and other research has found links between earworms and feelings of wellbeing, both before and while experiencing the inner tunes. Another study found that earworms occur more frequently for liked than for disliked songs. For most people, earworms don’t play for very long. If you happen to love your internal soundtrack, just sit back and enjoy it while it lasts.

9 Not-So-Pesky Facts About Termites

Termites get a lot of hate for chewing through buildings, but the little creatures are far more interesting—and ecologically valuable—than we often give them credit for. Unless, of course, you’re Lisa Margonelli, the author of Underbug: An Obsessive Tale of Termites and Technology, a new book that explores their amazing world. Here are nine facts about the highly social—and occasionally pesky—insects that we learned from the book.

1. THERE ARE FAR MORE TERMITES THAN PEOPLE ON EARTH.

Termite queens live up to 25 years, and can lay somewhere around 30,000 eggs a day. As a result, a single mound can be home to millions of individuals at a time. While the numbers vary from study to study, scientists estimate that the biomass of all the termites in the world is at least as great as that of humans.

2. MOST TERMITES AREN’T PESTS.

Of the 2800 named termite species in the world, the majority have no interest in eating your house. Only 28 species are known to chow down on buildings and infrastructure. Most are actually very beneficial to their ecosystems, clearing dead wood, aerating the soil with their intricate tunnel systems, and enhancing plant growth. Researchers have found that contrary to being pests, networks of termite mounds can help make dry environments like savannas more resilient to climate change because of the way termite mounds store nutrients and moisture, among other benefits.

3. TERMITES ARE GOOD FOR CROPS.

Termites can help make soil more fertile. In one study, researchers in Australia found that fields that were home to ants and termites produced 36 percent more wheat, without fertilizer, compared to non-termite fields. Why? Termites help fertilize the soil naturally—their poop, which they use to plaster their tunnels, is full of nitrogen. Their intricate system of underground tunnels also helps rainfall penetrate the soil more deeply, which reduces the amount of moisture that evaporates from the dirt and makes it more likely that the water can be taken up by plants.

4. TERMITES HAVE VERY SPECIFIC ROLES IN THEIR COLONY.

Each termite colony has a queen and king termite (or several), plus workers and soldiers. This caste system, controlled by pheromones produced by the reigning queen, determines not just what different termites do in the colony but how they look. Queens and kings develop wings that, when they’re sexually mature, they use to fly away from their original nest to reproduce and start their own colony. Once they land at the site of their new colony, queens and kings snap off these wings, since they’ll spend the rest of their lives underground. Queens are also physically much larger than other castes: The largest type of termite, an African species called Macrotermes bellicosus, produces queens up to 4 inches long.

Unlike their royal counterparts, most workers and soldiers don’t have either eyes or wings. Worker termites, which are responsible for foraging, building tunnels, and feeding the other castes in the nest, are significantly smaller than queens. M. bellicosus workers, for instance, measure around 0.14 inches. Soldier termites are slightly bigger than workers, with large, sharp mandibles designed to slice up ants and other enemies that might invade the nest.

5. TERMITES ARE ONE OF THE FASTEST ANIMALS IN THE WORLD.

Apologies to cheetahs, but termites hold the record for world’s fastest animal movement. Panamanian termites can clap their mandibles shut at 157 miles per hour. (Compare that to the cheetah’s run, which tops out at about 76 miles per hour.) This quick action allows tiny termite soldiers in narrow tunnels to kill invaders with a single bite.

6. TERMITES ARE SKILLED ARCHITECTS.

In Namibia, quarter-inch-long termites of the genus Macrotermes can move 364 pounds of dirt and 3300 pounds of water each year total in the course of building their 17-foot-tall mounds. Relative to their size, that’s the equivalent of humans building the 163 floors of Dubai’s Burj Khalifa, no cranes required. And that’s not even the tallest termite mound around—some can be up to 30 feet high. More impressively, termites cooperate to build these structures without any sort of centralized plan. Engineers are now trying to replicate this decentralized swarm intelligence to build robots that could erect buildings in a similar fashion.

7. TERMITES BUILD THEIR OWN AIR CONDITIONING.

Some termites have developed an incredibly efficient method of climate control in the form of tall, above-ground mounds that sit above their nests. Organized around a central chimney, the structures essentially act as giant lungs, "breathing" air in and out as the temperature outside changes in relation to the temperature inside. Thanks to these convection cycles, termites keep underground temperatures in their nest between roughly 84°F and 90°F.

8. TERMITES ARE FARMERS.

Humans aren’t the only ones cultivating crops. Termites farm, too. They’ve been doing it for more than 25 million years, compared to humans’ 23,000 years. Some species of termite have evolved a symbiotic relationship with Termitomyces fungi, growing fungus in underground gardens for food. When they fly off to create a new colony, termite queens bring along fungus spores from their parent colony to seed the garden that will feed their new nest. Foraging termite workers go out and eat plant material that they can’t fully digest on their own, then deposit their feces on the fungus for it to feed on. They can then eat the fungus. They may also be able to eat some of the plant material after the fungus has sufficiently broken it down. The mutually beneficial relationship has led some scientists to suggest that the fungus, which is much larger in both size and energy production than the termites, could in fact be the one in control of the relationship, potentially releasing chemical pheromones that lead the termites to build the mound they live in together.

9. TERMITES ARE MICROBIAL GOLD MINES.

As scientists begin to understand the huge role that micobiomes play in both the human body and the rest of the world, termites provide a fascinating case study. About 90 percent of the organisms in termite guts aren’t found anywhere else on Earth. In their hindgut alone, they host as many as 1400 species of bacteria. These microbes are so efficient at converting the cellulose-rich wood and dead grass that termites eat into energy, scientists want to harness them to make biofuel from plants.

This Live Stream Lets You Eavesdrop on Endangered Killer Whales' Conversations

Southern resident killer whales, which are usually found off the coasts of Washington, Oregon, and British Columbia, are an endangered species. If you're lucky, though, you might be able to hear a pod of the killer whales chattering away from the comfort of your own home. A website spotted by The Kansas City Star lets you live stream the calls of killer whales from your phone or laptop. Dubbed Orcasound, it uses hydrophones (underwater microphones) to pick up oceanic sounds from two areas off the coast of Washington.

On the website, listeners can choose between the two locations. One is the Orcasound Lab in Haro Strait, which is situated off the coast of Washington's San Juan Islands—the "summertime habitat" of this specific ecotype of whale, according to the website. The other location is Bush Point at the entrance to Puget Sound, where the whales pass through about once a month in search of salmon. However, that hydrophone is currently being repaired.

So what do orcas sound like? They're loud, and they do a whole lot of whistling, whining, and clicking. You can hear a snippet of what that sounds like in a four-minute podcast uploaded to the Orcasound site.

There’s no guarantee you’ll hear an orca, though. "Mostly you'll hear ships," the website notes, but there's also a chance you'll hear humpbacks in the fall and male harbor seals in the summer.

The live stream isn't just for educational purposes. It also serves as a citizen science project to help researchers continue their studies of southern resident killer whales, which are in danger of starvation as Chinook salmon, their main food source, die off.

The makers of Orcasound are urging listeners to email ihearsomething@orcasound.net anytime they hear killer whales or "other interesting sounds." They can also log their observations in a shared Google spreadsheet. Eventually, developers of the site hope to roll out a button that listeners can click when they hear a whale, to make the process easier for people to get involved.
